Abstract
In this chapter the elasticity boundary value problems in three spatial dimensions are considered. The topological derivative of the total potential energy for the perturbation in the form of a small spherical cavity \(B_{\varepsilon}(\widehat{x})\), with \(\widehat{x} \in \Omega \subset \mathbb{R}^{3}\) and \(\overline{B_{\varepsilon}} \Subset \Omega\), is obtained. Therefore, the topologically perturbed domain is given by \(\Omega_{\varepsilon} = \Omega \setminus \overline{B_{\varepsilon}}\).
